Drag & drop Queues page not working as a Page include

I have a drag and drop queues page built on the opportunity object that allows us to move opportunities easily through "stages" (followed this tutorial: http://help.skuidify.com/m/11720/l/217806-queue-component-custom-item-renderers ). Everything works great on this page when previewed. I then created an additional tab on our opportunity tab page to show this page via a page include and for some reason the "drop" function of the page does not work any more. Any suggestions?

Before digging too far here lets take care of the standard question: Are any model names repeated between the opportunity page and the drag and drop detail include? This will always cause problems. Usually very unexpected ones.
